CHlME RlNGING DEVICE.

SPECIFICATION forming part of Letters Patent No. 720,541, dated.February 10, 1903. Application filed August 1.1901. Serial No. 70,482.(No model.)

To all whom, it may concern.-

Be it known that I, HERMANN ALBERT WENDE, a citizen of the UnitedStates, and a resident of Buffalo, in the county of Erie and State ofNew York, have invented a new and Improved Chime-Ringing Device, ofwhich the following is a full, clear, and exact dein which similarcharacters of reference indi-" cate corresponding parts in all theviews.

Figure 1 is a diagrammatic view showing a chime-ringing mechanismembodying my; invention. Fig; 2 is a plan view showing actuating-leversemployed and the releasing de vices therefor. Fig. 3 is a section on theline a: m of Fig. 2. Fig. 4 shows one of the levergnides employed. Fig,5 is a section on the line y y of Fig. 3. Fig. 6 is a plan view of thekeyboard. Fig. 7 is a plan view of the circuit-closers employed; andFig. 8 is a crosssectional View with the keyboard thereon, also insection.

The mechanism comprises a series of levers 1, mounted to rock on a shaft2 and also having a slight lateral movement on said shaft, this shaftbeing supported in a frame 3, which may be placed at any desiredlocation or underneath the chime of bells. It will be understood that alever 1 will be provided for each bell or the hammer thereof.

From each lever 1 a transmission or draw rod ,4 extends to a connectionwith one arm of an angle-lever 5, from the other end of which a link 6extends to a connection with one member of an angle-lever 7, on theother section of which is mounted a bell-hammer 8, designed to strikeits bell 9. Arranged to rotate in the frame 3 is a tappet-carrying shaft10, which is kept in constant rotation during the ringing of the chimesby means of a suit- .are deflecting-posts 22.

able motor having connection with the baudwheel 11 on said shaft.Arranged on the shaft are tappet-arms 12,there being a series of suchtappet-arms arranged in a circular row for operating in connection witheach lever l, as will be hereinafter described.

From the forward end of each lever 1 an actuating-spring 13 extendsdownward to a connection with a fixed rod 14 in the frame 3, and eachlever 1 is locked in inoperative position by means of an armature-lever15, the several armature-levers being mounted to swing on a rod 16, andthese armaturelevers are held in engagement with the actuating-levers 1by means of springs 17. The armatures on the armature-levers coact withelectromagnets 18. Each armature-lever 15 at its upperend is providedwith a shoulder 19, which prevents. the actuating-lever from moving toofar down ward when engaged with said armature-lever.

Extended upward from the bottom of the frame 3 areguides for theactuating-levers. These guides are made inthe form of loops, and theupper portions-thereof are inclined laterally, as indicated at 21 inFig. 4. These lateral inclines are designed to swing the forward ends ofthe levers 1 into engagement with the armature-levers,'and it will benoted that when said forward ends swing downward under the impulse ofthe spring 13 the end of the actuating-lever will be moved toa line atone side of the armature-lever, so that when the circuit is openedthrough the electromagnet the said armatu re-lever in its backwardmovement will not contact or engage with the end of the actuating-lever,thus preventing its possible operation.

Extended upward from the bottom of the frame 3 and slightly forward ofthe shaft 10 At the upper end of each deflecting-post is a projection23, the side 24: of which is inclined upward and laterally, the upperend being directed away from the line of movement of the tappet-arms 12.The opposite side 25 of this projection is inclined downwardly andlaterally, the lower end being directed toward the line of movement ofsaid t-appet-"arms 12.

In the operation of the device as so far described when an electromagnetis energized by closing the circuit by a key mechanism TOG itsarmature-lever will be moved toward the magnet, thus releasing itsactuating-lever 1. The forward end of the actuating-lever will then bemoved downward by its spring 13, causing the throw of the bell-hammer.During this movement the rear end of the actuating-lever will moveupward and engage against the inclined side 24 of the projection 23 andmove up and over the top of the same, and the slight resiliency of theactuating-lever will cause its rear end to spring over to the oppositeside 25 of said projection and into the line of movement of thetappet-arm 12. One of said tappet-arms therefore will engage with theactuating-lever, moving its rear end downward, and consequently itsfront end portion upward, where it will be again engaged by the lockingdevice or armature-lever. When the rear end of the lever 1 passes downbelow the projection 23, it will again spring back to the opposite sideof said projection, and consequently out of the line of movement of thetappet-arm.

Arranged at any suitable place is a circuitcontrolling device comprisinga series of spring-contacts 26, arranged on a board 27. The severalelectromagnets 18 are connected at one end to these spring-contacts,while the other ends of the electromagnets are connected withcontact-points 28, arranged on said board 27. It may be here stated,however, that the several electromagnets may have one end connectionwith all of the spring-contacts 26. Mounted to move on the board 27 is akeyboard 29, and arranged on the keyboard are the actuating-keys 30 and31, the long keys 30 representing the full tones, while the short keys31 are for the sharps and fiats. From the several keys fingers 32 extenddownward for engaging with the circuit-closers 26. It will be noted thatthe keys on the .keyboard represent a scale, and by moving the keyboardalong the circuit-controller board changesin the scale may be quicklymade as desired.

With this mechanism the blow at a chime is instantly delivered andcannot be recovered; but the actuating-lever is immediately reset and isagain ready for operation at the will of the operator. In this machineafter installation no adjustments are required and there are no parts tobecome worn or loose. The device requires no closing or opening of ahigh-pressure electric current in a belfry or tower. Consequently thereis no danger of fire caused by the dangerous arc of such highelectric-power currents.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In a chime-ringing mechanism, a series ofindependent actuating-levers having connection with chime-strikers,electrically-com trolled locking and releasing mechanism for saidlevers, a tappet-shaft, tappet-arms carried by said shaft, and means formoving the ends of the actuating-levers laterally into the line ofmovement of said tappet-arms, substantially as specified.

2. In a chime-ringing mechanism, a series ofindependentactuating-levers,an armaturelever for each actuating-lever, for lockingthe same in withdrawn position, an electromagnet for releasing thearmature-lever from the actuating-lever, a guide for the actuating-leverarranged to move the end of said actuating-lever into engagement withthe armaturelever, springs for moving the actuating-levers in onedirection, and means for moving the actuating-levers to the originalposition, substantially as specified.

3. In a chime-ringing mechanism, a series of actuating-levers,connections between said actuating-levers and bell-strikers, springs formoving the actuating-levers in one direction, electrically-controlledlocking devices for the actuating-levers, deflecting'posts at one end ofthe actuating-levers, projections on the upper ends of said posts, theopposite sides of said projections being inclined in oppositedirections, a tappet-shaft, and tappet-arms carried by said shaft, therebeing a series of tappet-arms for each actuating-lever, substantially asspecified.

4:. In a chime-ringing mechanism, a series of actuating-levers, lockingdevices for the levers, electromagnets for releasing said l0ckingdevices, a circuit-controller comprising a series of spring-contacts,and a series of coacting contact'points, the said spring-contacts andcontact-points being in connection with the electromagnets, and akeyboard movable over the said contacts, substantially as specified.
